The smartphone market in 2024 is packed with high-end devices from Samsung, Apple, Google, and Xiaomi, all competing for the title of “best flagship.” Among them, OnePlus has built a reputation for delivering premium specs at a more affordable price. The OnePlus 12 continues this tradition, but with even more refinements—better cameras, a brighter display, and faster charging.
But is it still the best value flagship? Or have competitors like the Galaxy S24 and Pixel 8 Pro caught up in ways that make the OnePlus 12 less compelling? This in-depth review will analyze every aspect of the OnePlus 12—design, display, performance, cameras, battery life, software, and price—to determine whether it remains the top choice for buyers who want flagship performance without the premium price tag.
Design & Build Quality: Premium Yet Familiar
OnePlus has always balanced premium materials with practical design choices, and the OnePlus 12 follows this philosophy. The phone features a glass back with a frosted matte finish, which feels luxurious while resisting fingerprints. The aluminum frame adds rigidity without making the device too heavy—it weighs 220 grams, which is lighter than the iPhone 15 Pro Max (221g) but slightly heavier than the Galaxy S24+ (196g).
Key Design Features:
- Alert Slider: A signature OnePlus feature, now with improved tactile feedback for easier toggling between sound modes.
- Curved Display Edges: The 6.82-inch screen has subtle curves, enhancing grip but potentially causing accidental touches.
- IP65 Rating: Improved dust and water resistance over the OnePlus 11, but still not as robust as the IP68 on rivals.
- Haptics: The vibration motor is finely tuned, providing precise feedback for typing and gaming.
Comparison with Competitors:
- Samsung Galaxy S24 Ultra: More angular, with a built-in S Pen but a heavier titanium frame.
- Google Pixel 8 Pro: Softer, rounded edges with a distinctive camera bar.
- iPhone 15 Pro: Uses titanium for a lighter build but lacks the OnePlus 12’s matte texture.
While the OnePlus 12 doesn’t reinvent smartphone design, it offers a refined, premium feel that competes well against more expensive flagships.
Display: Brighter, Smoother, and More Vibrant
The OnePlus 12 features a 6.82-inch LTPO AMOLED display with a 2K (3168 x 1440) resolution, 120Hz adaptive refresh rate, and a staggering peak brightness of 4,500 nits. This makes it one of the brightest smartphone screens available, surpassing even the Galaxy S24 Ultra (2,600 nits) and iPhone 15 Pro Max (2,000 nits).
Display Highlights:
✔ Adaptive Refresh Rate (1Hz–120Hz) – Saves battery by lowering refresh rate when static content is displayed.
✔ Dolby Vision & HDR10+ Support – Enhances streaming quality on Netflix, Disney+, and YouTube.
✔ 10-Bit Color Depth – Over 1 billion colors for more natural gradients.
✔ PWM Dimming (2,160Hz) – Reduces eye strain in low-light conditions.
Real-World Usage:
- Outdoor Visibility: The high brightness makes the screen easily readable in direct sunlight.
- Gaming & Media: The combination of 120Hz smoothness and HDR support makes games and movies look stunning.
- Color Accuracy: The “Natural” mode is well-calibrated for accurate colors, while “Vivid” mode boosts saturation for a more eye-catching look.
How It Compares to Other Flagships:
| Feature | OnePlus 12 | Galaxy S24 Ultra | iPhone 15 Pro Max |
|---|---|---|---|
| Max Brightness | 4,500 nits | 2,600 nits | 2,000 nits |
| Refresh Rate | 1–120Hz LTPO | 1–120Hz LTPO | ProMotion (10–120Hz) |
| HDR Support | Dolby Vision | HDR10+ | Dolby Vision |
Verdict: The OnePlus 12 has one of the best displays on any smartphone, beating even more expensive rivals in brightness and smoothness.
Performance: Snapdragon 8 Gen 3 – A Speed Demon
The OnePlus 12 is powered by the Qualcomm Snapdragon 8 Gen 3, the fastest Android chipset in early 2024. Combined with up to 16GB of LPDDR5X RAM and UFS 4.0 storage, it delivers desktop-level performance in a smartphone.
Benchmark Scores (vs Competitors):
| Device | Geekbench 6 (Single/Multi) | 3DMark Wild Life Extreme |
|---|---|---|
| OnePlus 12 | 2,200 / 7,100 | 4,200 |
| Galaxy S24 Ultra | 2,100 / 6,800 | 3,900 |
| iPhone 15 Pro | 2,900 / 7,200 | 4,500 |
Real-World Performance:
- Gaming: Runs Genshin Impact at 60fps (Max Settings) without throttling, thanks to the 9,140mm² vapor chamber cooling system.
- Multitasking: Handles 20+ Chrome tabs, Discord, and YouTube simultaneously without slowdowns.
- App Launch Speed: Opens apps instantly, with no lag even after days of use.
Thermal Management:
Unlike some Snapdragon 8 Gen 2 phones (which overheated under load), the OnePlus 12 stays cool even during extended gaming sessions. This is due to:
✔ Larger cooling area than the OnePlus 11.
✔ Optimized heat dissipation through graphite layers.
Verdict: The OnePlus 12 is one of the fastest Android phones available, making it ideal for power users and gamers.
Camera System: Better, But Still Not the Best
OnePlus has historically lagged behind Samsung and Google in camera quality, but the OnePlus 12 makes significant improvements.
Camera Hardware:
- 50MP Main (Sony IMX890, OIS) – Great dynamic range and low-light shots.
- 64MP Periscope Telephoto (3x Optical, 6x Lossless Zoom) – Sharp details even at 10x zoom.
- 48MP Ultra-Wide (Sony IMX581) – Minimal distortion and good color consistency.
Photo Quality:
- Daylight Photos: Excellent detail and color accuracy, though Pixel 8 Pro still leads in HDR processing.
- Portrait Mode: Improved edge detection, but iPhone 15 Pro has more natural bokeh.
- Low-Light: Brighter than the OnePlus 11, but Galaxy S24 Ultra retains more shadow detail.
Video Recording:
- 8K@24fps and 4K@120fps options.
- Good stabilization, though not as smooth as iPhone’s Cinematic Mode.
Verdict: The OnePlus 12’s cameras are much better than before, but Pixel and Galaxy phones still lead in computational photography.
Battery Life & Charging: Unmatched Speed
The 5,400mAh battery provides 7.5–8 hours of screen-on time with 120Hz enabled.
Charging Speeds:
- 100W Wired (0–100% in 26 mins) – Faster than Galaxy S24 Ultra (45W) and iPhone 15 Pro Max (27W).
- 50W Wireless (Full charge in 45 mins) – No other flagship charges this fast wirelessly.
Verdict: The OnePlus 12 has the best charging of any flagship in 2024.
Software: OxygenOS 14 – Clean & Fast
- Near-stock Android with useful additions.
- 4 Years of OS Updates (matches Samsung).
- No bloatware, unlike some Galaxy phones.
Final Verdict: Best Value Flagship?
✅ Pros:
- Best display in its price range.
- Snapdragon 8 Gen 3 performance.
